Abstract: This application relates to a ray tracing apparatus and the apparatus includes a main ray tracing unit configured to generate an acceleration structure (AS) and configured to transmit scene data to perform a ray tracing operation for a part of the scene data and a plurality of sub ray tracing units being coupled in series, each except for a last sub ray tracing unit configured to relay the scene data to a next sub ray tracing unit and configured to perform a ray tracing operation on a different part of the scene data. Therefore, the ray tracing apparatus may include a plurality of chips to process a rendering for a 3-dimensional image in real time.

Abstract: A rendering apparatus and method are provided. The rendering method includes: reading a block, corresponding to a fragment, from among compressed blocks stored in a depth buffer, by considering frequency information corresponding to the fragment and prepared in advance; and performing a depth test for the fragment by considering the restored block.

Abstract: A method, medium, and system of rendering image data, including receiving three-dimensional space data for each pixel forming the image data, the three-dimensional space data including depth and color information values for each pixel, determining an order of rendering for a plurality of surfaces forming the image data in an order of the distance between a rendering viewpoint and the surface forming the image data, generating splat depth information values for each splat included in the surface forming the image data, according to the rendering order, and determining whether the splat included in the surface forming the image data is required to be blended and accordingly selectively performing a blending on the splat.
